SWE-Trail Uses History-Guided Trajectories for Coding Agent Training
October 31, 2026
SWE-Trail addresses redundancy in coding agent trajectory collection by using previous exploration and editing history to guide subsequent sampling. This approach aims to improve post-training data quality without introducing test-time advice dependencies that cause train-test mismatch.
